Pros:
Nice mix of open/technical, some elevation, a bit of water. Also a nice mixup in the throws required.
Gorgeous scenery, plus other activities in the park available.
Multiple tees on most holes.
Cons:
Wonky numbering system.
Not always clear where the next tee is, though this is nowhere near as bad as on some courses.
Older-style baskets sometimes blend into the background on the original 20 holes.
The "new" holes seem to be focused on being difficult, rather than being fun.
Other Thoughts:
This is one of the best courses in central Ohio. I wish that meant as much as it sounds like (none of my favorite courses are in the area), but it is a good, solid course. On my own, personal ranking system ("How far would you drive to play this one?") it falls in at "If you're heading to the area, it's worth going a bit out of your way to get to, but don't make a special trip for it."
As mentioned in the pros & cons section, this is a good course with a very nice mix of required shots in a very pretty park. There are no boring holes, the closest you get is a few mostly-open shots, which provide a nice counterpoint to the technical holes.
At least, that's the original 20 holes. The "new, hard holes" they put in... well, some people are going to love them, but I'm not one of those people. There were some decent holes in them, but I'm not one for 300-feet-across-water throws (lose way too many discs that way), nor do I see the point of 800' long holes, and seriously... I know the parking lot the course plays through sees essentially no use, but why put the course through the middle of it?
Anyway, as I said, some people will see those as advantages. I just skip the extra holes, it's not like you don't get enough fun in the rest of the course.
As others have mentioned, there's an extra hole with a letter designation in the middle of the course. There is also an unnumbered, unmarked hole after 18. Take a good look at the course map before throwing if you've never been there before.
